Why Choose the Pizzato CSAT-10V120-TF3 Safety Module?
The Pizzato CSAT-10V120-TF3 is a high-performance safety monitoring relay designed for advanced industrial machine safety systems operating on a 120 V AC control supply. Manufactured by Pizzato Elettrica, it is engineered to supervise emergency stop circuits, safety gates, interlock systems, and multi-channel safety architectures, ensuring reliable and controlled machine shutdown in hazardous environments.
This model belongs to the CS AT safety relay family and is designed for applications requiring Category 4 safety performance, PL e, and SIL 3 compliance. It features an expanded output structure with 3NO instantaneous safety outputs + 2NO delayed safety outputs, enabling both immediate machine stop functions and controlled run-down sequencing for complex automation systems.
The TF3 version provides a fixed 3-second delay function, making it ideal for systems that require a short controlled stopping time after a safety trigger, helping reduce mechanical stress and ensure safer machine shutdown behaviour. Its compact DIN-rail housing allows easy integration into industrial control panels and OEM machinery.

Key Features
- Pizzato CS AT safety relay series.
- 120 V AC supply voltage.
- Output configuration: 3 NO instantaneous + 2 NO delayed.
- Fixed timing safety function for controlled machine stop applications.
- Screw terminal connections for secure industrial wiring.
- DIN-rail mounting for control panel integration.
- Designed for complex machine safety architectures.
Reliable Safety Control for Industrial Systems
The CSAT-10V120-TF3 continuously monitors safety inputs such as emergency stop buttons, safety gate switches, and interlock devices. When a safety event occurs, it immediately activates safety outputs and maintains delayed outputs for a fixed 3-second interval, ensuring controlled machine shutdown with safe run-down behaviour.
This combination of immediate and timed safety switching improves operator protection, reduces mechanical stress, and supports structured stopping sequences in automated systems with higher output capacity requirements.
Typical Applications
- Advanced emergency stop (E-Stop) safety circuits.
- Multi-channel safety gate and interlock systems.
- Industrial automation control panels.
- OEM machine safety architectures.
- Production lines requiring controlled stop sequencing.
- Complex machinery safety systems with expanded outputs.
